Application filed June 16, 1913. Serial No. 773,953.

To all whom it may concern Be it. known that 1, MAX EPSTEIN, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, provement in Tank-Cars, of which the following is a specification.

My invention relates, more particularly, to tank;cars for transporting fluids of a character requiring that they be kept at a substantially uniform temperature, or shielded from changes in temperature of the surrounding atmosphere; and my object is to provide a construction of tank-car which shall .be strong and durable, and whereby the fluid transported therein shall beefi'ectually shielded against-influence of the surrounding atmosphere.

Referring to the accompanying drawings Figure 1 is a view in elevation of an end of a tank-car constructed in accordance with my invention. Fig. .2 is an enlarged section taken at the line 2 onFig. 1 and viewed in the direction of the arrow. Fig. 3 is a section :taken at the line 3 on Fig. 2 and viewed in the direction of the arrow. Fig. 4 is a broken section taken at the line 4 on Fig. 2 and viewed in the direction of the arrow, this View showing the details of insulating the dome-section of the fluidcontainin tank from the'housing for the latter; an Fig. 5, an end view ofthe fluidcontaini'ng' tank showing the manner of bracing a. filler member cooperating with the end "of the tank.

The under-frame of the car may be of any suitable construction, that shown being of a form in common use, and thus it is deemed unnecessary to explain the construction thereof, further than to' state that the frameinclud'es a channeled girder 6 which extends lengthwise of the car and is supported from the trucks thereof, this girder'supporting horizontally-disposed saddles 7 rigidly secured thereto, the top sides of these saddles being concaved to formrecesses into'which the superstructure of the tank-car and involving the parts hereinafter described, exte'n'd and are seated.

The superstructure of the car comprises, generally stated, an outer shell or housing 8, preferably of wood and cylindrical 1n form, its circular wall being formed of longitudinallyextending staves and the ends of the housingbein'g'in the form of heads 9 have invented a new and useful IIllmade up of edge-wise abutting sections 10, these heads 9 fitting at their circumference into chimes 11 formed about the inner periphery of the circular wall of the housing, the parts of the housing just referred to being held together in assembled relation by retaining hoops 12 and the housing being held in place on the under-frame of the car as by bands 8 which extend over the top of the housing and are secured at their ends to the under-frame as indicated at 8 i l The housing 8 is provided for inclosing a tank for receiving and storing the .material to be transported by the car, such tank being represented at 13 and preferably constructed of sheet-steel and of cylindrical form, the heads of the tank bein'gr'epresented at 14 and each preferably extern'all concaved as represented in Fig. .3 with i s outer margins flanged as represented at 15, at which flanges it fits within the circular wall of the tank 13 and is secured ther'einin any suitable manner as by riveting (not shown), the tank described thus havingcon' caved inset heads. The tank 13 is daused to be spaced throughoutits cylindrical side from the housing .8, as by spacing members 16 confined between the tank and housing, and the space thus provided between these parts is packed with insulating material, he hereinafter described.

It will be understood from the foregoing that the tank 13, when filled, is of relatively great Weight and provision must bem'a'd to prevent the tank from freely shifting-on the body of the czir. This result is prefer ably accomplished by the constru'ctiondisclosed in the drawings wherein the undrframe ofthe car is provided at op' os ite ends, as is usual in constructions 0 this character, with head-blocks 17. member 18 curved along its bottom to correspond With the contour of the inner circumference of .the side wall of thehousing 8, rests on the latter beyond the head's'ffl, and confined between each head-block 17 and each end of thehousing 8 and thead jacent plate-member 18 is a block19,"it"b'eing understood, that in the preferred construction illustrated, one of the blocks19 is provided at each end of the car to fill out the space between the head-blocks 17 and the ends of the housing 8, and that one of the plate-members 18 cooperates with each head9 of the housing, the'parts being p'ref- A plate erably so arranged that the stress exerted by the housing 8 tending to move it longitudinally, is communicated to the head-. blocks 17 through the heads 9. It is intended .that longitudinal movement of the tank 13 relative to the car be resisted by the head-blocks 17 and this is preferably accomplished by causing the ends of the tank 13 to cooperate either directly or indirectly with the heads'9. In the preferred arrangement illustrated a plate 20, preferably of metal, and located in the housing 8, extends between the inner side of each head 9 and the ends of the tank 13 as represented of one end of the tank in Fig. 3. In order to more efiectually resist the movement of the tank 13 relative to the car and distribute strains, I interpose-between the. concaved portion of each head 14 and the inner side of the adjacent plate 20, a block 21, whereby the area of the tank resisting the tendency to movement of the latter on the understructure is augmented. In order to prevent displacement of the blocks 21, as might occur where the heads 14 are concaved as illustrated, I prefer to brace these blocks as illustrated in the drawing, by means of bars 22 which are wedged between the upper surface of the blocks 21 and the diametrically opposed portion of the flanges 15 (Fig. 5).

As hereinbefore stated, the tank 13 is insulated from the housing 8, and this is effected by filling the spaces .provided, as described, between the tank and housing, with any suitable material, such as for example, hair-felt, the insulating material being interposed between the ends of the tank 13 and the housing aswell as between the cylindrical sides of these members in order that as complete insulation as possible of the tank 13 from the atmosphere be efiected. As is usual in tank-cars, the tank for the fluid is'equipped with a dome having a removable closure through which be introduced therein, such dome being reprzsggted at 22 and the removable closure a In order that effectual insulation of the tank 13 from the atmosphere be efiected it is necessary that the dome 22 also be insulated from the surroundin atmosphere and this is preferably accompdished by the following-described constructlonr The housing 8 is formed with an upwardly-extending ho low cylindrical section 24 which opens into the interior of the housing 8, this extension surrounding the dome 22 and being of such diameter that it will be spaced therefrom as indicated in Fig. 4. The top portion of the extension .24 is formed of two horizontally-disposed s aced plate-members 25 and 26 with a ring 2 interposed therebetween and fitting against the inner circumference of the extension 24. The plate members 25 and 26 contain rectangular openthe fluid may ings 28 and 29 which register with the closure .23 and in which is secured a rectangular frame 30, preferably downwardly taperas illustrated in Fig. 4. with the interior of the frame 30 is a plug 31 preferably formed of upper and lower plate-sections 32 and 33 spaced apart by a frame 34 to render the plug 31 hollow, as indicated at 35, for receiving any suitable heat-insulating material, such as hair-felt, the sides of the plug 31 being preferably covered with any suitable fabric, represented at 36, for insuring a tight joint between the plug and the frame 30. A cover 37, hinged as indicated at 38, on a block 39 secured to the plate section 25, cotiperates with the upper end of the frame 30 and in its preferred form is provided about its under-side with a rectangular frame 40, which, whenthe cover 37 is in closed position (Fig. 4) bears downwardly on a beading 41 carried on the upper surface of the plate-section 25. Any suitable insulating material is packed into the spaces between the dome 22 and the extension 24 as represented at 42; and also into the space indicated at 43 and afl'orded between the plate members 25 and 26 and into'the space 35, thereby effectually insulating the dome 22 from the surrounding atmosphere.

While I have illustrated and described a particular embodiment of my invention, ll do not wish to be understood as intending to limit it'thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new and desire to secure by Letters Patent isp 1. In a tank-car, the combination of its under-frame, head-blocks thereon, a housing on said under-frame and located between said head-blocks, said head-blocks and the heads of saidhousing for resisting longitudinal movement of said housing on said under-frame, and a tank in said housing in a position to be resisted by said heads under conditionstending to shift said tank longitudinally.
